### Please describe the problem.
|
||||
|
||||
Some remotes disappeared from `git annex info` after synchronising with a new repo.
|
||||
|
||||
### What steps will reproduce the problem?
|
||||
|
||||
1. have a nice repository full of remotes and special remotes
|
||||
2. create a new repository with `git init; git annex init; git reinit <some UUID from a previously lost repository>`
|
||||
3. sync the two repositories
|
||||
|
||||
Expected the result: restore the lost repository the its previous state.
|
||||
|
||||
Actual result: previous state available, but lost track of other repositories.
|
||||
|
||||
I suspect there may be a relation to an old "forget history" transition at play here, as the last commit on the git-annex branch is:
|
||||

||||

continuing transition ["forget git history","forget dead remotes","forget git history","forget dead remotes","forget git history","forget git history","forget dead remotes","forget git history","forget dead remotes","forget git history","forget dead remotes","forget git history","forget dead remotes"]
|
||||
```
|
||||
|
||||
So in short, some remotes that i never marked as dead seem to be caught in the whirlpool of `forget` transitions.
|
||||
|
||||
### What version of git-annex are you using? On what operating system?
|
||||
|
||||
5.20151208-1~bpo8+1 on debian jessie.
|
||||
|
||||
### Please provide any additional information below.
|
||||

||||
So here's what i could salvage from my terminal history. Note that window resizing may have truncated some lines. Apologies for the mess...

... in the last step, the external device disappeared and the transfer failed.

After reconnecting the device, I tried to synchronise its content with the content of another device, but that device is gone!

In my opinion, git-annex shouldn't have lost the following repositories:

Those are repositories that are in the git-annex history, but that don't have git remotes associated with them, for various reasons. I do *not* believe I have marked any of those as "dead" except maybe 3f6d8082-6f4b-4faa-a3d9-bd5db1891077. f8818d12-9882-4ca5-bc0f-04e987888a8d was used during the weekend to do my backups, so it's definitely not dead.
|
||||
|
||||
It is also interesting to note that even though `git annex info` doesn't know about the remotes, there is still tracking information about all of them (except the 3f one):

it's a mystery to me why that stuff disappeared from `git-annex info`.

### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
|
||||
|
||||
Yes! Git-annex works generally well and, even though i often report bugs here, i am still quite happy with it. :) --[[anarcat]]
